Abstract
Description
- The present invention relates to a machine for the formation of rolls of cotton-wool in compact form.
- The machines of this type (see GB-A-2 095 203) are also known under the name of cotton-wool compactors and have the task of packaging the cotton-wool in rolls of the most limited dimensions possible in view of their transport from the manufacturing plant to the place of usage.
- In known compactors of cotton-wool a layer of cotton-wool of normal thickness obtained at the end of the process is wound on a support core, so as to form a roll of large dimensions that is subsequently introduced in an outer sheath of polyethylene. The whole is then subjected to a reduction of transversal size by means of the diametric contraction of a cage of parallel rods placed round the wound roll and/or by extraction of air from the inside of the sheath.
- The result is a roll of reduced dimensions but with an irregular shape with the outer coating creased and partially deteriorated, that once returned to the original dimensions gives rise to a finished product that cannot be defined perfect.
- In view of this state of the art, the object of the present invention has been that of providing a machine that allows the formation of rolls of cotton-wool with minimum dimensions, perfectly cylindrical and with the outer coating absolutely intact.
- According to the invention such object has been achieved with a machine characterized in that it comprises a closed-loop conveyor belt having a horizontal upper branch on which there is placed a layer of cotton-wool to be wound, a pair of support rollers for said horizontal upper branch, first operating means to execute the displacement of said support rollers from a rest position with rollers reciprocally distanced to a working position with rollers reciprocally close to one another passing through an intermediate position of partial reciprocal closeness, support means for a freely-rotatable core destined for winding up the cotton-wool, second operating means that can be operated after the displacement of said support rollers in said position of partial reciprocal closeness to execute the descent of said support means of the core from a rest position above said upper branch of the conveyor belt to a position of partial lowering below said upper branch of the conveyor belt wherein the core has engaged and lowered a portion of said upper branch of the conveyor belt and a corresponding portion of the layer of cotton-wool passing between said support rollers so as to create a loop of said upper branch of the conveyor belt and of the layer of cotton-wool below said upper branch and said support rollers, third operating means to drive said conveyor belt to wind up the layer of cotton-wool round said core after a further displacement of said support rollers in said working position and while the descent of the core continues, and tensioning means associated with the conveyor belt to maintain the tension of the belt at a constant value suitable for pressing the cotton-wool as the core continues to move downward and the cotton-wool is wound on the core itself.
- A protective film of flexible material is preferably supplied on a terminal section of the layer of cotton-wool to be wound by the same machine round the roll of cotton-wool and then sealed so as to maintain the latter in a wound-up and compact condition when the roll itself has reached predetermined final dimensions and before said third operating means stop and said first and second operating means move in reverse to return said support rollers and said support means of the core to a rest position.
- In this way the constant-tension conveyor belt winds the cotton-wool progressively round the supporting core and at the same time it reduces its thickness, obtaining at the end a perfectly cylindrical roll already compacted and wound in a protective sheath, that needs no further treatments. The external coating of the roll thus formed is perfect, just as the finished product is free of all defects when, after transport, it is unwound and returned to the original dimensions by a suitable treatment, for example in a machine like that described in the European patent application No. 0674034 by the same Applicant.
- The features and advantages of the present invention will now be made more evident by the following detailed description of an embodiment thereof illustrated as a non-limiting example in the enclosed drawings, wherein:
- Fig. 1 shows an elevated view of a machine according to the invention in a condition at rest;
- Fig. 2 shows the machine in a side view, again in a condition at rest;
- Fig. 3 shows the machine again in elevation, during an initial step of its working cycle;
- Figs. 4 and 5 show a base part of the machine, again in elevation, during successive steps of its working cycle.
-
- The machine illustrated in the drawings comprises a base part 1 comprising a supporting
chassis 2 for a series of driving, support and transmission rollers for a closed-loop conveyor belt 3, for example in PVC with trapeze-shaped lateral guides. - As shown in particular in Fig. 1, a
first roller 4 constitutes a driving roller for theconveyor belt 3 and receives motion from a variable-speed motor 5. All the other rollers 6 - 14 in engagement with theconveyor belt 3 are idle and in particular the rollers 6 - 8 are simple transmission rollers, therollers 9 and 10 define a horizontalupper branch 15 of thebelt 3 and therollers roller 11 and with a pair oftensioning rollers vertical guides 18 under the action of a pair ofhydraulic cylinders 19, to define a device for tensioning the belt suitable for maintaining the belt itself at a constant tension, as will be better seen later. - With the
upper branch 15 of theconveyor belt 3 there are also in engagement twosupport rollers 20, that have their ends endowed withpinions 21 in step-engagement with respective toothed racks 22 (Fig. 2) and are rotatably supported byrespective slides 23 movable alonghorizontal guides 24 under the action of respective hydraulic cylinders 25 (Fig. 1). For the sake of accuracy, thesupport rollers 20 are displaceable from the rest position and greatest reciprocal distance of Fig. 1 to the working position and greatest reciprocal closeness of Figs. 4 and 5, passing through an intermediate position of partial reciprocal closeness that is shown in Fig. 3. - Above the base part 1, in a position intermediate between the
support rollers 20 in the rest position, there is arranged a head part 26 (Figs. 1 and 2), that comprises a pair ofpillars 27 suitable for acting as guides for a pair ofslides 28 moving vertically, that carryrespective idle chucks 29 destined for supporting respective ends of acore 30 in turn destined for supporting the roll of cotton-wool to be formed. The twoslides 28 are attached torespective belts 31, that extend in a closed ring between anupper pulley 32 endowed with amotor 33 and alower idle pulley 34 and they also carry acounterweight 35. - In operation, with the machine in the condition at rest of Figs. 1 and 2, a
cardboard core 30 is loaded between thechucks 29 and a layer of cotton-wool 36 to be wound round thecore 30 is introduced on the horizontalupper branch 15, as shown in Fig. 3. - The
cylinders 25 are then driven to perform the displacement of thesupport rollers 20 from the rest position of Fig. 1 to the partial closeness position of Fig. 3, where between the tworollers 20 there remains only space sufficient for the passage of the twochucks 29 with thecorresponding core 30, whose descent under the action of themotor 33 has in the meantime begun. - When the
core 30 meets the initial section of the layer of cotton-wool 36 that is superimposed over theupper section 15 of theconveyor belt 3 above the space defined between therollers 20, and then continues its descent, the core itself moves downward both the cotton-wool and the conveyor belt, thus determining the partial winding of the layer of cotton-wool round the core itself and the formation of a loop of the conveyor belt, as shown in Fig. 4. - The
rollers 20 are then displaced to the working position and greatest closeness of Fig. 4 and theload cells 16, detecting through theroller 11 an increase in the tension of theconveyor belt 3, execute through the cylinders 19 a partial ascent of theslides 17 with thecorresponding tensioning rollers - Simultaneously with the attainment of the position of greatest closeness on the part of the
support rollers 20, themotor 34 executes through thedriving pulley 4 the operation of theconveyor belt 3, that together with the further descent of the twochucks 29 and of thecorresponding core 30 determines the progressive winding of the layer of cotton-wool 36 round thecore 30. In the meantime the tensioning device consisting of theload cells 16, of thecylinders 19, of theslides 17 and of thetensioning rollers conveyor belt 3 at a constant value suitable for ensuring the winding of the cotton-wool with a minimum thickness but without deteriorating the cotton-wool itself. - Round the
core 30 there is thus formed a roll of cotton-wool 37 (Fig. 5), whose final dimensions are fixed, for example, by means of an encoder associated with themotor 33 used to move thechicks 29 downward. - Just before the attainment of the abovementioned final dimensions of the
roll 37, afilm 38 of polyethylene or other suitable flexible plastic material for packaging is superimposed over the terminal section of the layer of cotton-wool 36 so as to be wound round theroll 37 and thus form a protective sheath for the roll itself, that is lastly sealed by means of the application of a suitable glue (in a manner not shown but known in itself). - At that point the
cylinders 25 drive thesupport rollers 20 back to their rest position and immediately afterward themotor 33 executes the return ascent of thechucks 29 with thecorresponding core 30 androll 37 wound in thefilm 38. - The cycle of the machine is thus over and a packed
roll 37 is thus obtained, that is perfectly cylindrical, with a suitably reduced diameter and with the surface absolutely perfect. Further processes before transport are not necessary and, once the place of usage has been reached, the cotton-wool can be removed from the protective sheath, unwound and returned with no defects to the original thickness, for example through the machine described in the European patent application No. 0674034 of the same Applicant
